Slack is looking for a Staff Software Engineer to join our Desktop team within the Architecture & Systems organization. While most frontend roles focus on building user‑facing features, this role is dedicated to building the Desktop Framework — the architectural foundation that underpins the Slack desktop client across all platforms. The team is heavily involved within the Electron open‑source project, ensuring the continued success and sustainability of the Electron ecosystem on behalf of Slack.

• Strategic Leadership
  :
  Lead cross‑functional initiatives across Electron and at Slack associated with increasing developer productivity, OS level stability, performance, or security alongside desktop and frontend stakeholders.
• Technical Standards
  :
  Contribute to key architectural decisions to adapt our existing frontend and desktop infrastructure to support new product features.
• Navigating Ambiguity
  :
  Thrive in ambiguity, often identifying and offering solutions to problems, like framework migrations or rendering bottlenecks, that are not yet evident to the leaders who presented them.
• System Health
  :
  Maintain and improve the core systems that power the Slack desktop client and Electron framework, including Slack and Electron‑based infrastructure and tooling.
• Mentorship & Culture
  :
  Build a safe space for learning and serve as a skilled and trusted mentor to engineers across the organization, developing the ability to coach new leaders rather than just individual contributors.
• Cross‑Functional Execution
  :
  Collaborate with teammates across engineering to identify, define, and solve strategically important initiatives, acting as a leader in communication to de‑escalate conflicts and drive consensus.

• 10+ years of experience writing client‑side code (React + Typescript) for modern web applications at scale.
• Deep Chromium experience, or experience contributing to large‑scale open‑source projects.
• Development at Scale:
  Worked in a large‑scale, shared codebase with hundreds of contributors, establishing patterns that allow other teams to contribute effectively without friction. Wrote understandable, testable code with an eye toward maintainability and scalability.
• Strategic Architecture:
  Built complex systems and tooling, leading technical design that guides the best decisions across the team.
• Business Alignment:
  Exceptional communication skills, tying technical infrastructure to company goals such as performance, reliability, and developer velocity. Facilitated dialogue between junior and senior members to surface blockers.
• Technical Breadth:
  Experienced with performance profiling and debugging tools for web‑based desktop applications. Familiarity with desktop development and able to explain technical trade‑offs and complexities.
• Self‑Awareness:
  Provided constructive feedback and graciously received it to improve self and team culture.
• Eager to learn and teach.
• Empathy:
  Understanding that the perfect solution is informed by the people who will be building on your work, rather than purely technical merits.

• Contributions to engineering reputation externally (e.g., blog posts, speaking at conferences, open‑source contributions).
• Developed on Windows and maintained build infrastructure for Windows desktop applications.
• Experience in fast‑paced and dynamic product development environments.
